Despite the vast body of research examining the relationship between full-day kindergarten attendance and children's outcomes, little is known about the effects of full-day kindergarten on children with disabilities (i.e., students with 1 of the 13 categories of disabilities recognized under federal law). This study fills this research void by…

Background: Whether and to what extent racial/ethnic disparities in attention-deficit/hyperactivity disorder (ADHD) diagnosis occur by kindergarten entry is currently unknown. We investigated risk factors associated with an ADHD diagnosis by kindergarten entry generally, and specifically whether racial/ethnic disparities in ADHD diagnosis occur by…

Using the recently available wave of a large nationally representative sample of American elementary school children (ECLS-K data), this study examined the relationship between 6-7 year old students' behaviors exhibited in the 1st grade (approaches to learning, interpersonal skills, externalizing and internalizing behavior) and their reading and…

This study challenges the belief that homogeneous ability grouping benefits high-ability students in cognitive and social-emotional development at the expense of their low-ability peers. From a developmental point of view, the authors hypothesize that homogeneous grouping may improve the learning behaviors and may benefit the literacy learning of…

Adam Wright, Michael A. Gottfried, and Vi-Nhuan Le demonstrate empirically that minority teachers have a positive impact on the "social-emotional development" of American minority kindergarten children. Their analyses of 2010-2011 data from the Early Childhood Longitudinal Study focus on measurable effects in four social and affective…

We revisit Harry L. Gracey's perspective of kindergarten as academic boot camp where, at school entry, children acquire the student role through a structured program of activities. We provide further insights into the crucial mechanisms of socialization that occur in U.S. kindergartens by examining the relationship between within-class ability…

Understanding disparities in school readiness among America's children when they begin kindergarten is critically important, now more than ever. In today's 21st century global economy, it is expected that the great majority of children will complete high school ready to enter college or begin a career, and assume their civic responsibilities. This…

Prior research has unearthed a link between early education and care (EEC) experiences and worse behavioral functioning for children, yet the research has not clearly delineated whether this link is due to early entry into care (timing), extensive hours of care (extent), or use of center-based care (type). Using a nationally representative sample…

The authors used a large sample of children (N [is approximately equal to] 7,400) participating in the Early Childhood Longitudinal Study-Kindergarten Cohort (ECLS-K) to estimate kindergarten children's academic achievement growth trajectories in reading and mathematics. The authors were particularly interested in whether the growth trajectories…

Reading is a necessary skill in our modern society and is increasingly critical for success in our highly technological society. Yet many children from low-SES backgrounds struggle to develop reading proficiency (Lee, Grigg, & Donahue, 2007) and continuing concerns about this pervasive relationship has led to an increased focus on creating…

Objective: Whether and to what extent racial/ethnic disparities in attention-deficit/hyperactivity disorder (ADHD) diagnosis occur across early and middle childhood is currently unknown. We examined the over-time dynamics of race/ethnic disparities in diagnosis from kindergarten to eighth grade and disparities in treatment in fifth and eighth…

This paper aims at investigating the causal effects of social behaviors on subsequent reading growth in elementary school, using the "Early Childhood Longitudinal Study-Kindergarten" ("ECLS-K") data. The sample was 8,869 subjects who provided longitudinal measures of reading IRT scores from kindergarten (1998-1999) to fifth…

This study uses data from the Early Childhood Longitudinal Study, Kindergarten Class of 1998-1999 (ECLS-K) to analyze competencies that children need to master by the end of elementary school, the extent to which they are doing so, what might be done to improve their performance, and how this might affect their ultimate ability to earn a living…

Background/Context: Children with attention-deficit/hyperactivity disorder (ADHD) provide a test case through which to investigate psychosocial school compositional effects. Characterized by developmentally atypical levels of inattention, activity, and impulsivity, the condition often manifests itself, and is identified, in school settings and is…

Recent empirical research has found that children's noncognitive skills play a critical role in their own success, young children's behavioral and psychological disorders can severely harm their future outcomes, and disruptive students harm the behavior and learning of their classmates. Yet relatively little is known about wide-scale interventions…
